Abstract
An optical module comprising: a plurality of active optoelectronic components each one mounted on a respective printed circuit board (PCB), wherein each active optoelectronic component is associated with a respective different optical channel; a plurality of optical assemblies, each one is substantially aligned over a different respective optical channel; and a spacer separating the active optoelectronic components and PCBs from the optical assemblies, wherein the optical assemblies are attached by adhesive directly to an optical assembly-side surface of the spacer. A first active optoelectronic component is separated, by the spacer, from a first optical assembly by a first distance and a second active optoelectronic component is separated, by the spacer, from a second optical assembly by a different second distance. Also contemplated is a method for fabricating an optical module that comprises: modifying a height of one or more extensions on a spacer to adjust for at least one of a focal length or tilt of at least one optical channel.
